Handle all-null columns #260

Closed dandanlen closed 4 years ago

dandanlen commented 4 years ago

Example from the Aircloak attack server, Clinic dataset:

                select
                    min("flags"),
                    max("flags"),
                    count(*),
                    count_noise(*)
                from "visits"

All columns are null, so the min and max are null, which the parser doesn't expect...

Fixing this should fix #249
